Factory Crimp Die Caliber 338 Win. / 338-06 LEE for Reloading and Precision Shooting
Lee Factory Crimp Die for .338 Winchester / .338-06 Caliber
This precision-engineered crimp die is meticulously designed to provide an optimal factory crimp on your metallic and semi-metallic cartridges, ensuring superior bullet retention and consistent chambering.
Utilizing advanced crimping technology, this die firmly secures the projectile to the case neck with unparalleled grip strength, surpassing other dies on the market, while maintaining the integrity of the brass case without causing deformation or neck splits.
The die features a specialized crimping collar that compresses the case mouth into the bullets cannelure, delivering a secure, uniform crimp that enhances cartridge reliability and feeding in both semi-automatic and lever-action firearms.
Extensive ballistic testing conducted by Lee has demonstrated that employing a Factory Crimp Die results in a more consistent pressure curve during ignition, which directly translates into improved shot-to-shot accuracy and tighter groupings on target.
Remarkably, this die also improves accuracy with bullets lacking a factory cannelure by providing a controlled crimp that prevents bullet setback and ensures consistent bullet pull pressures.
The enhanced crimping effect elevates the initial bullet release pressure, requiring a higher threshold before the projectile begins to move forward in the barrel. This increased resistance stabilizes internal ballistics, producing a more uniform pressure curve and reducing velocity variations.
Designed specifically for use in semi-automatic and lever-action rifles chambered in .338 Winchester or .338-06, this die is indispensable for reloaders seeking to maximize performance and reliability in their handloads.
Please note: Shellholder is not included with this die and must be purchased separately.
Constructed from high-grade hardened steel, this crimp die offers exceptional durability and long service life under rigorous reloading conditions.
Compatible with reloading presses that accept the standard 7/8"-14 thread size, ensuring broad compatibility with most popular press models.
Packaged in a protective plastic case to safeguard the die from damage and contamination during storage and transport.
